[Andrewshkovskii]

How can i remove/recolor/change border-radius of this encircled element of headerView?

Current css for tableWidget:

QTableView{
border : 0.5px solid gray;
border-radius : 25px;
}
 QHeaderView::section:first {
	 background-color: qlineargradient(x1:0, y1:0, x2:0, y2:1,
									   stop:0 #616161, stop: 0.5 #505050,
									   stop: 0.6 #434343, stop:1 #656565);
	 color: white;
	 border: 1px solid #6c6c6c;
	 border-radius : 25px;/*does not work*/
	 padding-left: 4px;
	 margin-left  : 25px;
 }

QTableView{
border : 0.5px solid gray;
border-radius : 25px;
}
 QHeaderView::section:first {
	 background-color: qlineargradient(x1:0, y1:0, x2:0, y2:1,
									   stop:0 #616161, stop: 0.5 #505050,
									   stop: 0.6 #434343, stop:1 #656565);
	 color: white;
	 border: 1px solid #6c6c6c;
	 border-radius : 25px;/*does not work*/
	 padding-left: 4px;
	 margin-left  : 25px;
 }
